How an over-the-air update made Quilt’s heat pumps more powerful


Quilt's software update unlocked an additional 20% heating and cooling capacity for all of its heat pumps, including those installed in customers' homes.

Isaac McQuillen, the engineer who led the capacity increase project, worked most recently at Lucid Motors, where he managed heating and cooling for both passengers and batteries. Once the team realized they had room to spare, they set about testing the new parameters on in-house units to validate both performance and reliability. Quilt’s updates included both software and firmware that runs on the main processor and microcontrollers scattered throughout the indoor and outdoor units.
